+==== Fixes
+* Fixes an issue where opening the rule details flyout for a deleted rule crashed the {security-app} when the rule was missing `severity_mapping` or `risk_score_mapping` values ({kibana-pull}278545[#278545]).
+* Fixes an issue where {kib} assets from an installed integration package (such as dashboards used by prebuilt detection rules) could remain stale across a {kib} upgrade because {fleet} never overwrote existing assets on reinstall  ({kibana-pull}277953[#277953]).
+* Fixes an issue where the **Source event** link in an alert's **Highlighted fields** section failed to open the document when its source index had been restored (for example, from a cold or frozen tier) and renamed  ({kibana-pull}277703[#277703]).
+* Fixes a denial of service (DoS) vulnerability in {kib}'s Timeline bulk export functionality ({kibana-pull}260265[#260265]).
+* Updates the bundled `curl` library in {elastic-defend}, improving the stability of network operations on Linux.
+* Fixes an issue in {elastic-defend} that could result in incomplete addresses in network event tracking.
+* Fixes an issue where {elastic-defend} on macOS could not recover its subscription to network events after a failure, because the failed subscription was sticky and no recovery was attempted.
+* Fixes a crash in {elastic-defend} when the Kafka broker rejected a document that was too large.
